>> this is the fifth year of our partnership with another planet entertainment, where another planet puts on probably the greatest music festival in america for three days here in golden gate park. >> we work with them a lot to prevent and not have any problems. and what we have done with them is have roads built and have pieces under whatever equipment is parked. they do all of that. and then when it gets removed, they have very little damage. >> for me as a gardener and having to stay here and work after they leave, i am more than happy when i see their greening team come through and green everything up. >> we have given them pieces that they can use, and pieces that they can't use. so we are allowing them, again, because we have irrigation in the ground so they can use, and if they put up a tent they can stake a tent in some places, they can't stake a tent in other places.
